The Aurora is Jacob Boehme's first book. It introduces many of his ideas, and some of Boehme's explanations about nature, human and divine, can only be found in this, his first book.
There are many themes in common with the theosophical neo-platonic tradition of Ammonius Saccas, Plotinus, Porphyry, Iamblichus and Proclus, as well as with the Kabbalistic tradition. Hierarchies, the emanation (generation) of Cosmos, angelic kingdoms, trinities, signatura, ideation, duality, transformation can all be found with Boehme, as with the other traditions. Keep in mind that Jacob Boehme uses a very veiled style of writing. He had to do that, in order to survive the narrow-minded world of the fundamentalist Christians, at war with each other at that time. He certainly acknowledged the idea of the Christ potency within the human being (indeed, the New Testament refers to this too), a transformation and realization possible for those oriented to the right way of life.
